Appin Road upgrade between Rosemeadow and Mt Gilead

The upgrade would be funded by the NSW Government Housing Acceleration Fund and Lendlease to unlock new housing at Mt Gilead and improve safety and access for local residents and through traffic.

Planning is currently underway to deliver a 5.4-kilometre road safety upgrade between Mount Gilead and Ambarvale which includes intersection upgrades, widening part of the road from two to four lanes, and construction of new intersections to provide access to the approved Figtree Hill community project.

In addition, two koala underpasses and additional fauna fencing are proposed to increase protection for the local koala population.

The community is invited to provide feedback on the Addendum Review of Environmental Factors (A/REF) from Tuesday 22 November until Tuesday 13 December 2022. Community feedback will help us understand what is important to customers and the community. To have your say visit
